Title
(EN) MAGNETIC MARKER SYSTEM
(FR) SYSTÈME DE MARQUEUR MAGNÉTIQUE
(JA) 磁気マーカシステム
Abstract
(EN)
Provided is a magnetic marker system (1) for implementing vehicle control either for assisting with driving operation of a vehicle performed by a driver or for autonomous driving independent of a driver's operation. Magnetic markers (10) are laid along a road such that the orientations of the magnetic poles thereof are alternately inverted, and are positioned with gaps therebetween along the road such that the magnetic fields of the adjacent magnetic markers (10) mutually interfere. Accordingly, detection reliability of vehicle-side magnetic markers (10) can be improved without the need to increase the magnetism of the magnetic markers (10).
(FR)
L'invention concerne un système de marqueur magnétique (1) permettant de mettre en œuvre une commande de véhicule pour assister une opération de conduite d'un véhicule effectuée par un conducteur ou pour effectuer une conduite autonome indépendamment de l'opération d’un conducteur. Des marqueurs magnétiques (10) sont placés le long d'une route de façon à ce que les orientations des pôles magnétiques de ceux-ci soient inversées de façon alternative, et sont positionnés avec des espaces entre eux le long de la route de façon à ce que les champs magnétiques des marqueurs magnétiques adjacents interfèrent mutuellement. Par conséquent, la fiabilité de détection des marqueurs magnétiques côté véhicule (10) peut être améliorée sans devoir augmenter le magnétisme des marqueurs magnétiques (10).
(JA)
運転者による車両の運転操作の支援、あるいは運転者の操作に依らない自動運転のための車両制御を実現するための磁気マーカシステム(1)において、磁気マーカ(10)は、道路に沿って交互に磁極の向きが反転するように敷設されていると共に、道路に沿って隙間を空けて隣り合う磁気マーカ(10)の磁界が干渉し合うように配置され、これにより、磁気マーカ(10)自体の磁力を抑えつつ車両側の磁気マーカ(10)の検出確実性が向上されている。
